• The blue light portion of the visible spectrum is most likely to scatter in the eye, causing discomfort and hazy illusion.

The CPF GlareCutter product is not described in terms of a specific wavelength cut-off. Its purpose is to serve patients who are beginning to experience light sensitivity problems outdoors. These patients don't require as much blue light attenuation as traditional CPF products provide. This additional blue light leakage allows the GlareCutter to be more cosmetically pleasing with minimal color distortion.

CPF (Corning) GlareControl lenses are chemically tempered to meet FDA impact resistance requirements, but they are NOT unbreakable or shatterproof.

GlareControl lenses do not pass some ANSI traffic signal requirements.

Check before driving... For safety's sake, your patients should be sure they can distinguish the colors in traffic signals before driving. GlareControl lenses, like any strongly tinted lenses, should not be worn for night driving. CPF® 550 and 550XD lenses are not recommended for any driving, night or day.
